几内亚苏阿皮蒂大坝混凝土温控浅析

Analysis on Concrete Temperature Control of Souapiti Dam in Guinea

几内亚苏阿皮蒂水利枢纽项目为碾压混凝土重力坝,工期紧,混凝土量大。工程所在区域旱季(11月~4月)、雨季(5月~10月)气候分明,月均温差不大。根据工程现场温度、湿度等环境条件与中国存在较大差异的特点,采取了与国内常规做法有差异的混凝土温控措施,取得了较好的效果,为在类似地区混凝土温度控制积累了经验。

The dam of Souapiti Hydro Project in Guinea is a RCC gravity dam with tight construction time and large concrete pouring volume.The climate in project area is clearly distimct between the dry season(November to April)and rainy season(May to October),and the monthly average temperature difference is smaller.Because the environmental conditions such as temperature and humidity are more different to China,the concrete temperature control measures that are different from conventional practices in China are adopted and good results have been achieved,which has accumulated experiences for concrete temperature control in similar areas.
